What are three things you could do if you were asked to become an advocate for health and wellness?

For starters, you must live up to what you fight for, so adopting a healthy lifestyle is the first obvious step. Also, considering the absurdly broad scope of the "health" definition (from the WHO, for example), you would have to decide on a specific focus. (i.e. alternative medicine? Nutrition and fitness? Access to global healthcare? and so on).
Among the career paths you could pick, there are:
*Becoming a health educator, by writing or broadcasting TV/ Youtube shows on wiser health choices; 
*Visiting countries where people lack basic resources in nutrition and diet, urban sanitary infrastructure, and/or healthcare advances (like vaccines); or perhaps other places where there has been a rise of non-trasmissive chronic diseases (e.g. obesity, hypertension, diabetes). The purpose is really to educate people on ways to overcome the causes and to bring awareness to the problems.
*And finally, you can be a personal trainer/dieter to individuals or groups.

I hope this helps! 

Yes violent video games can increase the risk of the person wanting to try out the things in reality , in real life . the person may be mad and want revenge and is playing the video game and the video may give more ideas of what to do sounds confusing but yes it does increase the influence sadly on violence out there . there is much evidence of many incidents where violence has happened sadly , like the columbine school shooting on april 20 of 1999 r.i.p to the innocent lives lost may they rest in peace ❤️also violent video games you can choose your choices on who to shoot and what to do and what to do not to get caught like gta 5 no hate on it i'm personally a big fan but you can choose to do bad or good on the game just like real life. people might illusion it in real life n try it out because in the video game it seems so realistic.
